IIIPROVZED COUPLING.

The Schedule referred to'in these Letters Patent and making part of thename.

Be it known that I, A. B. THOMPSON, of Owego, county of Tioga, and Stateof New York, have invented a new and improved Oar-Coupling; and Ido'hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanyingdrawings makingpart ofthis specification, and to the letters of refere nce marked thereon. Y v

My invention consists in constructing a car-coupling,

. asshown, the hody'or principal part of which is made of cast-iron,nearly of the usual form, externally, and 1 common links are also used,but, instead of employing a pin, the link is caught and held by apeculiar-shaped hook. The hook is operated by alever, and theattendantneed not go between the cars to couple, detach, or, in coupling, toraise and lower the link to couple cars varying in height.

1 To enable others'skilled-in the art, or that to which back from thelink to'the pin 4?, turns at a right angle, and descends through anopening in the piece A, and also through a hole in the lever 0, which isattached to the bottom of the draw-head.

The lever o is pivoted at one end to a lug or ear cast on one side ofthe draw-head; the lever then crosses beneath and extends sufficientlyfor an attendant todraw-head A, and the hook, after going' operate itwithout necessarily going between the cars to do so.

On the lever'is a ro1ler,-c, Figures 1 and 4, which moves ina curvedpath on the under side of the drawhead, and the lever is held firmly upby means of a spiral spring beneath it, and surrounding the part of thehook D, which descends through the lever, and a sufficient distancebelow it, to receive the spring.

In uncoupling, the lever is moved forward, which lifts-thejhook, and.the link may be withdrawn, but,

it is desired to back a car into a switch, the lever is thrown forward,and remains in that position by means of the friction-wheel sinking intoa depression in its path, where it isheld by the spiral spring.

Cars to be left at a distance may be uncoupled without danger,-bygrasping the lever as a train is passing at considerable speed.

In'coupling, the lever is moved back, which depresses the hook; the hookforces down the inner end-of the link, and the mouth of the draw-head isconstructed to act as a fulcrumto elevate the outerend of the link tothe proper height to enter the draw-head of the car coming up. a

. What I claim as my invention, and desire to secure by Letters Patent,is-- The combination of the hook D and the lever O, with its spring androller 0, arranged to operate in the draw-head A, substantially as andfor the purpose herein specified.
